Solid shells, 4cm l& w, whiter near umbone getting redish / brown towards the outsite. Radiating ribs are rough but not spiny.
No interactions present.
Since the days of the Collins guide the spiny cockles have had their names changed to Acanthocardia.
Its difficult to separate A.echinata from A.aculeata on the basis of a photograph of the outside of the shell. Both species are recorded in Red Wharf Bay.
